I am aware that rootkits are MAJOR security issues. Sadly, I do not have any way to reformat and re-install my OS. Anyways, nothing bad has happened yet, but I hear this one is nasty. I scanned last night with MBAM, and the log had two lines of this rootkit.trace of seneka. I am very, very scared that my computer is jeopardized.

Here is my MBAM log.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

No. Try not. Do... or do not. There is no try.

Thats all that showed up.

To fully remove this rootkit, do you think it is best to just reinstall and reformat my harddrive?

Let's dig deeper

Please download gmer.zip and save to your desktop.
  • Extract (unzip) the file to its own folder such as C:\Gmer. (Click here for information on how to do this if not sure.)
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security program drivers will not conflict with gmer's driver.
  • Click on this link to see a list of programs that should be disabled.
  • Double-click on gmer.exe to start the program.
  • Allow the gmer.sys driver to load if asked.
  • You may be prompted to scan immediately if GMER detects rootkit activity.
  • If you are prompted to scan your system click "Yes" to begin the scan.
  • If not prompted, click the "Rootkit/Malware" tab.
  • On the right-side, all items to be scanned should be checked by default except for "Show All". Leave that box unchecked.
  • Select all drives that are connected to your system to be scanned.
  • Click the Scan button to begin. (Please be patient as it can take some time to complete)
  • When the scan is finished, click Save to save the scan results to your Desktop.
  • Save the file as gmer.log and copy/paste the contents in your next reply.
  • Exit GMER and re-enable all active protection when done.

Your rootkit was old and looks like it's long gone

There are plenty of newer ones out now that might require a reload/format?

The Rootkit.Trace might be a laftover or even a failed install?

So, you think my computer is safe? It would be very very relieving if it was. I've heard that a rootkit is very hard to delete. And I have not really heard about Seneka, and that the cases that did have Seneka were nasty. I' just veyr worried. :thumbsup:. Like, could it hav opened any backdoors to my system?

Without any further evidence in a log, I doubt you had the full blown infection, which was quite nasty some months back.

It's a constant cat and mouse game between malware and security programs, staying updated is critical.

SO what is your opinion? Should i reformat or do you think it is relatively safe that I can just continue on using it the way it is?

Yes those look like they were from the same infection and the new detections are just broken remnants

Without any other current signs of infection I would have to assume that your system is OK.

The actual rootkit is gone or never installed.

So once the rootkit is gone, then my computer is back to being somewhat secure correct?

Hello.

Yes I agree the infection was not installed successfully as explained and expanded more in my PM.

So do you think from the lines of the MBAM log that I did have the full infection? Da Chew says that my computer is probably OK, so does that mean that any backdoors the rootkit may have opened should be closed now?

It seems that the executable file was not there but just leftover files that were not removed. Those files itself in theory cannot do anything without any 'guidance' from something else.

Although the infection seems it was not installed, I would still change any passwords especially if you do banking or any financial things. If the rootkit indeed was not installed successfully then I would too say that your computer is fine, however without knowing the EXACT facts I can not promise that it is clean and secure.

If you want to be safe, it would still be the best option to format. Alternatively you can post in the HJT-Malware Removal forum to make sure you are free from malware.

EDIT: Here's some information on rootkits if they do get installed:

Unfortunatly One or more of the identified infections is a Rootkit/backdoor trojan.

IMPORTANT NOTE: Rootkits and backdoor Trojans are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. You should change each password by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because this malware has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS.

I wouldn't fully trust it and would keep a close eye on it.

No. Try not. Do... or do not. There is no try.
